In the paper was presented direction for use geodesy, cartography and photogrammetry products, like are Digital Terrain Model (DTM), Digital terrain’s Cover Model and digital orthophoto to determination of river valley hydraulic characteristic. DTM was used to direct description of geometry of water flow region on the two-dimensional hydrodynamic model RMA2 from the SMS software package – the mesh nodes of hydrodynamic model were imported from DTM. Also it was found that digital orthophoto and Digital terrain’s Cover Model were useful to determination of material types areas, with which roughness values were combined. Digital Photogrammetric Workstation ImageStattion ZIV was the primery equipment, which was used to generation DTM and creation digital orthophoto.
